LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 283,399, dated August21, 1883.

` Application filed October 27, 1882. (No model.)

.To all whom t may concern:

Be it known that I, FRIDERICH Janncirr, a citizen of the United States,residing at Erie, in the county of Erie and State of Pennsylvania, haveinvented certain new and useful Improvements in Lubricating Devices forSteam- Engines 4and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention consists in providing certain improvements on thelubricator shown in Letters Patent No. 259,022, issued to me June 6,1882. These improvements relate to the construction of the oil cup orreservoir, and to the means for operating the pump by which the oil isdrawn from the reservoir and injected into the steam-chamber. Theconstruetion of the pump and the operation of the same is not changed inthis construction.

In the drawings, Figure l is a perspective view of a steam-enginecylinder and steamchest, and shows my invention in place thereon. Fig. 2is an elevation view of the oil-reservoir, with the central part invertical section.

The reservoir consists of a glass body, A, with metal cover and bottom BB, which are held together by a central stem or post, D, and a nut, C.(See Fig. 2.) The lower end of the post D is provided with ascrew-thread, c, by which it is connected with the pipe F, and ascrew-thread, d', which screws into the bottom B. The post' D is tubularat its lower end, from which tube are openings e e into the reservoir.The upper end of the post is also tubular, and opens through a hole, e,into the reservoir. The nut Gis tubular, and is finished on top with acup, H, which serves as a funnel for filling the reservoir. The nut alsoserves to clamp the cover and bottom B Bl firmly upon the glass cylinderA, and proper packing or joints being provided, the reservoir will be sotight as to hold oil.

On the outside of the cylinder A, between the parts B B, are gage-barsGr, which are put in place when the parts of the reservoir are puttogether. rIhese gage-bars are notched and numbered. The inner angles,f/ g, of these notches represent ounces (fluid) of capacity of thereservoir, and the outer angles, g g, will then represent half-ounces.These and push in the pump-piston.

gages are so numbered as to show the consumption of oil, and, togetherwith the means provided for regulating the consumption, constitute anessential feature of my invention. There are two of these gage-bars,simply for convenience. More could bc used, or only one, if desired.

, In the patent above referred to the piston of the oil-pump is workedby a lever connected with some of the working parts of the engine. Inthis construction now shown the pump-piston 8 is provided with a spring,4, which will move it out after it has been pushed in. The spring shownis a coil-spring; but other forms may be used. The means for moving theoilpump piston in are as follows: Clamped or otherwise fastened on thevalve-stem T is a standard or arm, I, or, if wanted, this may be on thepiston-stem or cross-head, as shown by dotted lines; but in most casesit will be found preferable to put it on the valve-stem. Attached tothis standard through the medium of the arm B, or some similar device,is a ram, S, or tappct-rod having a head, S. The device by which thistappet is connected with the standard I? will vary in form and styleaccording to the arrangement of parts of the engine and the relativeposition ofthe pump; but the essential feature will be that they willhold the tappet or ram S, so that as the engine moves it will cause thetappet to strike upon The head of the piston is provided with a screw orextension bolt, y, having a buffer-head, I; or this may be on the ram inplace of being on the piston. Its purpose is to'regulate or adjust thelength of the stroke of the piston 8.

In order to prevent noise a rubber buffer, 9, is put in the head of thebolt y, or it may be put in the head of the tappet S. rIhc arm It, whichholds the tappet, is made adjustable by a bolt and clamp-nut, o", and aslot, E', and the length of the tappet can be adjusted by a screw, r, sothat the tappet can be made to hit fairly on the head l of the pistonand move it in the proper distance, and the variations of stroke whichmay be wanted can be effected by adjusting the lbolt y. So it will beseen that the oil-pump piston is driven in by a tappet or ram connectedwith the moving parts of the engine, and it is drivenout by the reactionof the spring 4.

IOO

The lubricator is supported on the side of the steam-chest by a bracket,XV, which has a clamp, formed on its outer end, for the purpose ofgrasping and holding the cylinder of the pump 7 The bracket beingdistinct from the pump, it can be attached to it from either side, andin this way will serve as well on right or left engines.

. That I claim as new is l. The combination, in a lubricating apparatus,of the transparent cylinder A, having the top and bottom held in placcby means substantially as described, and gage-bars held in place by saidtop and bottoni, for the purpose set forth.

2. In a lubricating apparatus, substantially as shown, the combinationof a graduated oilreservoir with a pump for drawing the oil from saidreservoir, and having adjustable parts, substantially as shown, toregister with the graduated parts on the reservoir,whereby the length ofits piston-stroke can be regulated so as to regulate thc amount of oilit will pump at each stroke, whereby the rate of consumption oi' oil canbe observed and regulated.

3. In a lubricating apparatus substantially as shown` an oil-reservoirhaving combined therein, as shown, the following elcments: the

cylinder A, top and bottom B B, post D, with screw-threads c, d', and d,and having tubular ends with openings e e', and the tubular nut C, withcup H thereon.

4. In a lubricating apparatus substantially as shown, thecombination,with the oilpump, of the spring 4, applied to the piston ofsaid pump in a manner as shown, to move it out, an adjusting-screw, y,with buffer-head l, by which the length of the stem of said pumppistoncan be adjusted, a tappet bar or ram,
